the art to WlllCh lIIVBDiJlOIl appertains, In Figs, 5 and 6 in lieu of the washers 8 1-05 and to others who recognize the law of equibinding plates 13 are used. These plates librium in rotating bodies. V have arcuate concentrically-disposed flanges In the drawings forming a part of this 10 which fit over the side walls of the housspecification, Figure 1 is an edge view of a ing, and the bolts 6 preferably have heads H polishing wheel and balancing mechanism adapted to seat below theinner faces of the balancing weights within which they are placed, and so arranged that when the weights are in proper position a slight space will intervene between the side of the wheel and said weights.

At intervals through the web or flattened portion 1 of the balancing casing, screw or bolt holes are formed in close proximity to the inner wall 9 of said housing, and through these holes screws or bolts 11 and 12 as occasion may require, are used to secure the bal ancing mechanism to a Wheel. If the wheel is of heavy fibrous material such as leather, for instance, screws, as 11, are used to attach the balancing mechanism to the wheel, and where a buffing wheel of cloth or similar material is used, small bolts, as 12, (see. Fig. 4) pass from said mechanism through said wheel and are secured by means of nuts, in the customary manner for securing bolts, as shown.

Preferably two slots 3, as described, are used in a mechanism, as set forth. However, three slots may be used to good advantage. It is advantageous to place at least two counterbalancing weights with bolt attachments in a slot, especially where two slots are used, as by this means the weights may be moved along in their housing to effect a counterbalancing of the wheel with a minimum of both time and labor.

A mechanism as disclosed is economical in many ways. It saves time in effecting the marily of stampings it is comparatively cheap to produce owing to its mode of manufacture.

The drawings show, and we have described, a preferred embodiment of our counterbalancing mechanism. However, it would be obvious to those skilled in mechanics that various changes in minor details could be resorted to for effecting a like operation of the device, and we reserve the privilege to design and carry into practice any reasonable modification of the invention disclosed.

Having, therefore, described our invention, what we claim as new and desire to secure by Letters Patent, is z- A balancing device having in combination a disc-shaped body with a peripheral rectangular groove opening on one side, saidgroove having centrally-disposed arcuate slots formed through its bottom, arcuate weights carried in said groove, bolts passing through said slots and engaging said weights, binding plates passing over said bolts and nuts run onto said bolts over said ably secured within the groove of said disc, substantially as described.
